com Patent No. 65,609, dated June 11, 1867.

TO ALL WHOM I'l MAY CONCERN:

Be it lrnown that we, R. ROSS and B. E. LEHMAN, of Bethlehem, Northampton county, Benusylvania, have invented an `improvement in Oil-Cups;` and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

Our invention consists of an oil-cup constructed in the peculiar manner fully described hereafter, so that it may he easily manipulated,- and so that the oil may be freely discharged from it in a pure state.

In order to enable others skilled in the art to make and use our invention, we will now proceed to describe its construction and operation. On reference to the accompanying-drawing, which forms a part of this specificatioui I Figures I and 2 arevertical sections of our improved oil-cup.

Figure 3, a sectional plan on the line 1=2, iig. l.

Figure 4, the eamo on .the line 3 4, iig. 1.

Figure 5, the same on the line 5 6, ng; Q.; and

Figure 6, a detached portion-of the oil-cup.

Similar letters refer to similar ports throughout the several views: V

A is the mouth of the oil-cup, and B the reservoir. D is a hollov.7 spindle provided with a suitable handle, E, above which is the hea-d a, of a set-scre.v,` F, the threads of the latter being adapted tointernal threads in the upper end of the spindle D, the interior of which communicates through a lateral opening, b, with the externa-l air, the lower` en d of the set-screw forming a valve adapted to a seat, y, in the spindle. This spindle D passes through a ring, C, which is notched 'on the under side, forming projections which rest in the mouth A of the cup, so that the oil may have a free passage through the notches to the reservoir B under the circumstances describedhereafter. Between the mouth A. and the ring intervenes an annular piece, H, of wire gauze or perforated plate. Between the ring' C and the under side ofthe handle E intervenes a spiral spring, I, the tendency of which is to elevate the spindle D. That part of thespindle which passes through and isarranged to slide in the neck d of the vessel is cut away-to the form shown in tig. 3, so that there may bel a free communication between the reservoir B and month Aof t-he cup when the spindle is depressed. At the lower end of thespindle D is an enlargement, f', in which is a transverse hole, 7L, communicating with the interior of the said spindle,`

and in the end of the enlargement is a square orifice for the reception of the upper, square end of a cap, k, between a shoulder on which, and the end of the enlargement of the spindle, intervenes the spiral spring fm. In the cap k is a conical recess for the reception of a tapering projection, n, on the upper end of a branch, M, to

which the oil-cup is secured, this branch as w'ell a's its projection being hollow, and having a lateral communica-- tion,]1, with a lateral opening, p', in the cap fc, and consequently with-the interiorl of the oil reservoir B, under the circumstances referred to hereafter. When the several parts are in the position shown in iig.f2, the communication between the mouth and reservoir B is closed,as the valvef of the spindle D is maintained in contact with the seat e bythe spiral spring '121. If a supply' of oil has to be discharged from the reservoir B through the branch M, the spindle D is turned by' mcaps of the handle E until thc openingp of the cap k coincides with the openingp of the branch M, when a free passage is nfordedfor the escape of the oil. When the reservoir B has to be replenished with oil, thcspindle D is turned until the communication between the-reservoir'and the branch M is closed, when the operator deprcsses the spindle D by placing his-hand on the head a of the set-screw F, at

4the same time turning the latter, thereby elevating its lower end from the seat in ,the spind1e,vwhen air has free access to the interior of the reservoir B through the opening b and through the: interior of the spindle and transverse passageh, so that whatever oil is poured into the mouth A will at once passthrough the wire gauze strainer A in a pure state to the reservoir below. The strainenis maintained in its place during the movements of the spindle by the spring I, hut may be readily detached when the spindle is to be removed.v By this arrangement of the strainer and spring lthe use of a set-screws or other additional appliances for securing the strainer is avoided. v

When the pressure upon the spindle is withdrawn, it will be at once elevated to its former position by .the spiral spring m, and the communication between theA mouth A and the reservoir B will be closed. The spiral spring m serves to maintain the oep tight on the projection n, and the movement of the cap is limited by a pin, 9;, on the bottom ofthe Cup projecting into a, recess in the cap.

We ldo not claim broadly on oil-cup hai-ving o hollow stem with openings closed by a valve through which nil is admitted to af reservoir, neither do we claim broadly n. strainer in combination with an oil-cup, but We claim as our invention, and desire to secure by Letters Patent- 1. v'l'he combination of the spindle D, its valvef, cap c, spring m, projection n, and passagespp, the whole being constructed and arranged in respect to the mouth and reservoir ofthe oil-cup substantially as and for the purpose herein set forth. l

2. The combination of the above and the hollow spindle D, its vent-hole b, :mnd the set-screw F, for the purpose specified.

3. The ring C, restingl With'its notched under edge in the mouth A, and forming :t rest for the spring I, all as set forth. l

4. The detachable annular strainer H, constructed and combined with the ring C, spindle D, and spring I, its described.

In testimony whereof we have signed our names tothisspeciication in the presence of two subscribing witnesses.
